Reaktionsschritte

This Mg-P-ZSM-5/Al2O3 (5 g) was packed in a quartz fixed-bed flow reactor, and the ethylphenol mixture containing m- and p-ethylphenols obtained in Example 1 (Table 4; raw material) was charged as the raw material together with water (raw material/water weight ratio=1/1) at a reaction temperature of 450° C. and with WHSV=8 hr-1. The products were separated into gaseous and liquid products, the quantities of each product was measured and compositions were determined by gas chromatography. The total product composition was calculated from the quantities and compositions of the gaseous and liquid products. The compositions of the reaction products are shown in Table 4. The liquid product thus obtained was distilled with an Oldershow type distillation column with 25 plates, and the m-and p-ethylphenol fraction was collected to give m-ethylphenol with a purity of 98.6 wt%. The impurities were mainly of p-ethylphenol.
